V. Course Overview Unit 1 Content Area: Science Unit Title: The Nature of Science Target Course/Grade Level: Integrated Science/ 9th Grade Unit Summary: Science is defined as the knowledge obtained by exploring events and conditions in the natural world.

Learning Targets Disciplinary Core Ideas: PS1.A: Structure and Properties of Matter Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. (HS-PS1-1) The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns, the repeating patterns of this table reflect patterns of outer electron states. (HS-PS1-1) The structure and interactions of matter at the bulk scale are determined by electrical forces within and between atoms. (HS-PS1-3) PS2.A: Forces and Motion Newton’s second law accurately predicts changes in the motion of macroscopic objects. (HS-PS2-3) Momentum is defined for a particular frame of reference; it is the mass times the velocity of the object. (HS-PS2-2) If a system interacts with objects outside itself, the total momentum of the system can change; however, any such change is balanced by changes in the momentum of objects outside the system. (HS-PS2-2, HS-PS2-3) Science and Engineering Practices: Developing and Using Models Modeling in 9 – 12 builds on K – 8 experiences and progresses to using, synthesizing, and developing models to predict and show relationships among variables between systems and their components in the natural and designed world(s). Develop a model based on evidence to illustrate the relationships between systems or between components of a system. (HS-PS1, HS-PS2) Using Mathematical and Computational Thinking Mathematical and computational thinking in 9 – 12 builds on K – 8 experiences and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent and model data. Simple computational simulations are created and used based on mathematical models of basic assumptions. Use mathematical or computational representations of phenomena to describe explanations. (HS-PS1, HS-PS2) Constructing Explanation and Designed Solutions Constructing explanations and designing solutions in 9 – 12 builds on K – 8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories. Construct an explanation based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, theories, simulations, peer review0 and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future. (HS-PS1, HS-PS2) Apply scientific reasoning to link evidence to the claims to assess the extent to which the reasoning and data support the explanation or conclusion. (HS-PS1, HS-PS2) Engaging in Argument from Evidence Engaging in argument from evidence in 9 – 12 builds on K – 8 experiences and progresses to using appropriate and sufficient evidence and scientific reasoning to defend and critique claims and explanations about the natural and designed worlds(s) Arguments may also come from current scientific or historical episodes in science. Evaluate evidence behind currently accepted explanations or solutions to determine the merits of arguments. (HS-PS1, HS-PS2) Obtaining, Evaluating and Communication Information Obtaining, evaluating and communicating information in 9 – 12 builds on K – 8 experience and progresses to evaluating the validity and reliability of the claims, methods and designs. Communicate scientific ideas (e.g. about phenomena and/or the process of development and the design and performance of a proposed process or system) in multiple formats (including orally, texturally, and mathematically). (HS-PS1, HS-PS2) Connections to Nature of Science Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena A scientific theory is a substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment and the science community validates each theory before it is accepted. If new evidence is discovered that the theory does not accommodate, the theory is generally modified in light of this new evidence. (HS-PS1, HS-PS2) Models, mechanisms, and explanations collectively serve as tools in the development of a scientific theory. (HS-PS1, HS-PS2) NGSS#: Next Generation Science Standard: HS-PS1-4 Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship amount the net force on a macroscopic object, its mass, and its acceleration. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. HS-PS1-7 HS-PS2-1 HS-PS2-5 Unit Essential Questions How do scientific discoveries contribute to the development of new technologies? What are some problems that have been solved by science and technology? What new problems and opportunities have arisen by the use these new technologies? What are the main branches of natural science and do they relate to each other? What is the relationship between science and technology, scientific laws and theories? How mathematical formulas and models help us to understand scientific principles, laws and theories? Define and give examples of critical thinking skills. What are the main steps / methods scientists use in their investigations? What is a hypothesis? What is a controlled experiment? What are the SI base units of measurement? Unit Enduring Understandings Scientific knowledge is gained and developed through observations, investigations and measurements of events and processes occurring in the natural world. Natural science can be classified into three main branches with fields of study that are interdisciplinary, connected with each other. Practical technological developments have their foundation on basic scientific knowledge of the natural world. Scientific laws and theories are supported by repeated experiments and data analysis. Mathematical formulations and models are used to represent natural events and predict outcome of natural processes. In the scientific method, a scientist asks a question about a natural event, collects data related to the event, formulates a hypothesis, perform experiments, draw relevant conclusions and, if necessary, modify his hypothesis according to the results of the experiments. In a controlled experiment, all possible variables are kept constant except the variable that is relevant to the experiment hypothesis. How do we properly and safely use lab measuring tools? What are the main lab safety rules and procedures? What kind of data is best described as a line graph, pie graph? Give an example from everyday experiences that could be displayed as a line graph and a pie chart. What are dependent and independent variables? Give an example. What is the difference between accuracy and precision? Why is scientific notation useful? A common, standard SI Metric System of units of measurements is used so that data can be shared worldwide without reservations as to their consistency and integrity. Line graph is used when we want to show the changes over given time period. We would use line graph to represent temperature changes during a chemical reaction. Pie graph is used when we want to show parts of a whole, such as percentage of each element in the mineral calcite. The dependent variable depends on the independent variable. Example: heart rate is the dependent variable because it depends on the age of the person. The age of a person is the independent variable because changes in age affect heart rate. Accuracy is the extent to which a value approaches the true value while precision is the degree of exactness of a measurement. Scientific notation is useful for writing very large and very small measurements because it uses powers of 10 instead of strings of zeros. Unit Learning Targets Students will ... Compare and contrast the main branches of physical science. Explore the interdisciplinary nature of current scientific and technological activities. Explain how science and technology depend on each other. Define and give examples of scientific laws and theories Describe how scientific models and mathematical formulations help us in the understanding of scientific laws and theories. Mathematical, physical, and computational tools are used to search for and explain core scientific concepts and principles. Interpretation and manipulation of evidence-based models are used to build and critique arguments/explanations. Revisions of predictions and explanations are based on systematic observations, accurate measurements, and structured data/evidence. Mathematical tools and technology are used to gather, analyze, and communicate results. Empirical evidence is used to construct and defend arguments. Scientific reasoning is used to evaluate and interpret data patterns and scientific conclusions. Refinement of understandings, explanations, and models occurs as new evidence is incorporated. Data and refined models are used to revise predictions and explanations. Science is a practice in which an established body of knowledge is continually revised, refined, and extended as new evidence emerges. Science involves practicing productive social interactions with peers, such as partner talk, whole-group discussions, and small-group work. Science involves using language, both oral and written, as a tool for making thinking public.

Curriculum Development Resources : Click the links below to access additional resources used to design this unit: www.khanacademy.org phet.colorado.edu Unit 2 Content Area: Science Unit Title: Physics Target Course/Grade Level: Integrated Science/ 9th Grade Unit Summary: The understanding of motion and energy is a basic tenet of how Newton’s First, Second and Third Laws of Motion operate in the natural world. Students will be able to calculate force, mass and acceleration through the understanding of these laws. They will also be able to calculate the amount of energy an object contains and determine the amount of work the object can perform. Temperature is the measure of the amount of kinetic energy in an object commonly referred to as heat energy. This energy is conserved when it is transferred from one substance to another. Students will be able to measure the amount of heat in an object using the substance’s specific heat capacity. Primary interdisciplinary connections: ELA/ Literacy: WHST.9 – 12.2 Writing informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes. (HS-PS2-6) WHST.9-12.7 Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation. (HS-PS1-3) 21st century themes: Scientific investigations and technological developments on new materials, devices and processes used in various areas of society such as, consumer products, health care, communications, agriculture and industry, transportation and entertainment. Unit Rationale: The understanding of motion, forces, energy and the inter-relationship between them are fundamental to the understanding of Newton’s Laws. The understanding of the conservation of mechanical and heat energy is fundamental to all aspects of science. Learning Targets Disciplinary Core Ideas: PS2.A: Forces and Motion Newton’s second law accurately predicts changes in the motion of macroscopic objects. (HS-PS2-1) Momentum is defined for a particular frame of reference; it is the mass times the velocity of the object. (HS-PS2-2) If a system interacts with objects outside itself, the total momentum of the system can change; however any such change is balanced by changes in the momentum of the objects outside the system. (HS-PS2-2, HS-PS2-3) PS2.B: Types of Interactions Newton’s law of universal gravitation and Coulomb’s law provide the mathematical models to describe and predict the effects of gravitational and electrostatic forces between distance objects. (HS-PS2-4) Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic field; electric charges or changing magnetic fields cause electric fields. (HS-PS2-4, HS-PS2-5) PS3.A: Definitions of Energy Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms. (HSPS3- 1),(HS-PS3-2) At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy. (HSPS3- 2) (HS-PS3-3) These relationships are better understood at the microscopic scale, at which all of the different manifestations of energy can be modeled as a combination of energy associated with the motion of particles and energy associated with the configuration (relative position of the particles). In some cases the relative position energy can be thought of as stored in fields (which mediate interactions between particles). This last concept includes radiation, a phenomenon in which energy stored in fields moves across space. (HS-PS3-2) PS3.B: Conservation of Energy and Energy Transfer Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system. (HS-PS3-1) Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems. (HS-PS3-1), (HS-PS3-4) Mathematical expressions, which quantify how the stored energy in a system depends on its configuration (e.g. relative positions of charged particles, compression of a spring) and how kinetic energy depends on mass and speed, allow the concept of conservation of energy to be used to predict and describe system behavior. (HS-PS3-1) The availability of energy limits what can occur in any system. (HS-PS3-1) Uncontrolled systems always evolve toward more stable states that is, toward more uniform energy distribution (e.g., water flows downhill, objects hotter than their surrounding environment cool down). (HS-PS3-4) Science and Engineering Practices: Using Mathematics and Computational Thinking Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. Simple computational simulations are created and used based on mathematical models of basic assumptions. Use mathematical representations of phenomena to describe explanations. (HS-PS2-2), (HS-PS2-4) Constructing Explanations and Designing Solutions Constructing explanations and designing solutions in 9–12 builds on K–8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories. Apply scientific ideas to solve a design problem, taking into account possible unanticipated effects. (HS-PS2-3) NGSS#: Next Generation Science Standard: HS-PS2-1 Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration. Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system. Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current. Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media. HS-PS2-2 HS-PS2-4 HS-PS2-5 HS-PS3-1 HS-PS3-5 HS-PS4-1 HS-PS4-3 Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other. Unit Essential Questions Imagine that you could ride a baseball that is hit high enough and far enough for a home run. Using the baseball as a reference frame, what does the Earth appear to do? Joshua skates in a straight line at a constant sped for one minute, then begins going in circles at the same rate of speed, and then finally begins to increase speed. When is he accelerating? Describe a situation in which unbalanced forces are acting on an object. What is the net force on the object, and how does the net force change the motion of the object? Explain how the Law of Inertia relates to seat belt safety. Using Newton’s second law explains why the gravitational acceleration of any object near Earth is the same no matter what the mass of the object is. Define momentum, and explain what the Law of Conservation of Momentum means. Determine if work is being done in these situations: a) lifting a spoonful of soup to your mouth; b) holding a stack of books motionless above your head; c) letting a pencil fall to the ground. Describe how a lever can increase the force without changing the amount of work being done. Water storage tanks are usually built on towers or placed on hilltops; why? Using the concepts of kinetic and potential energy explain why a child on a swing needs to push from time to time. Define absolute zero in terms of kinetic energy of particles. Which substance will have the greatest temperature change with the addition of 1000 J of heat: 1 kg of water or 1 kg of iron? Explain the three ways heat can be transferred from one substance to another. Unit Enduring Understandings When an object changes position in comparison to a stationary reference point, the object is in motion. Circular motion is acceleration because of the constant change of direction. An unbalanced force must be present to cause any change in an object’s state of motion or rest. Inertia is the property of matter that resists change in motion. Gravitational force between two masses strengthens as the masses become more massive and rapidly weakens as the distance between them increases. When one object exerts an action force on a second object, the second object exerts a reaction force on the first object. Forces always occur in action-reaction pairs. Work is done when a force causes an object to move. This meaning is different from the everyday meaning of work. Power is the rate at which work is done. The mechanical advantage of a machine describes how much the machine multiplies force or increases distances. Energy is the ability to do work. Energy readily changes from one form to another. Absolute zero is the temperature at which the kinetic energy of a particle is at its lowest. One gram of iron will have a greater temperature change than the one gram of water because the specific heat capacity states that it takes 4186 J of heat to change the temperature of one kg of water by one degree while it takes only 449 J of heat to produce the same change in iron. Conduction, the transfer of heat through touch; convection, the transfer of heat by movement of a fluid and radiation, the transfer of heat by rays are the three ways heat can be transferred from one substance to another. Unit Learning Targets Students will ... Explain the relationship between motion and a frame of reference. Related speed to distance and time. Distinguish between speed and velocity.

(HS-PS1-3), (secondary to HS-PS2-6) PS1.C: Types of Interactions Nuclear processes, including fusion, fission, and radioactive decays of unstable nuclei, involve release or absorption of energy. The total number of neutrons plus protons does not change in any nuclear process. (HSPS1- 8) Forces at a distance are explained by fields (gravitational, electric, and magnetic) permeating space that can transfer energy through space. Magnets or electric currents cause magnetic field; electric charges or changing magnetic fields cause electric fields. (HS-PS2-4, HS-PS2-5) PS3.B: Chemical Reactions Chemical processes, their rates, and whether or not energy is stored or released can be understood in terms of the collisions of molecules and the rearrangements of atoms into new molecules, with consequent changes in the sum of all bond energies in the set of molecules that are matched by changes in kinetic energy. (HSPS1- 4),(HS-PS1-5) In many situations, a dynamic and condition-dependent balance between a reaction and the reverse reaction determines the numbers of all types of molecules present. (HS-PS1-6) The fact that atoms are conserved, together with knowledge of the chemical properties of the elements involved, can be used to describe and predict chemical reactions. (HS-PS1-2), (HS-PS1-7) Science and Engineering Practices: Using Mathematics and Computational Thinking Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. Simple computational simulations are created and used based on mathematical models of basic assumptions. Use mathematical representations of phenomena to describe explanations. (HS-PS2-2),(HS-PS2-4) Constructing Explanations and Designing Solutions Constructing explanations and designing solutions in 9–12 builds on K–8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories. Apply scientific ideas to solve a design problem, taking into account possible unanticipated effects. (HS-PS2-3) NGSS#: Next Generation Science Standard: HS-PS1-1 Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay. HS-PS1-2 HS-PS1-4 HS-PS1-7 HS-PS1-8 Unit Essential Questions How do mixtures and pure substances differ? Why is a change of state of a substance a physical change? How does heat affect the state of matter of a substance? What are the basic components of an atom? How is the periodic table arranged? What happens when the number of subatomic particles changes in an atom? How does the information on the periodic table tell the number of subatomic particles in each element? How does the structure of a compound affect its properties? How do atoms bond? What is a chemical reaction? What is the significance of balancing a chemical equation? Unit Enduring Understandings Mixtures are made of more than one substance which are not chemically combined. A change in state does not change the substance, only the kinetic energy of the particles changes. Heat energy speeds up particle motion, which causes substances to expand. Protons and neutrons make up the nucleus of the atom, electrons are found in orbitals outside the nucleus. Elements are grouped by energy level (period/ row) and valence electrons (group/ column). A change in the number of protons within an element results in a new element through radioactive decay. Neutron changes cause isotope formation. A change in the number of electrons forms ions. The atomic number gives the number protons; neutral atoms contain the same number of protons and electrons. The atomic mass number is the sum of the number of protons and neutrons contained in the nucleus of the atom. Ionic bonds form rigid structures with high melting points; covalent bonds form substances with lower melting points. Atoms bond to become stable by filling their valence shells by forming ionic or covalent bonds. A chemical reaction is the rearrangement of atoms by breaking and or forming bonds to create new substances. Chemical equations are balanced in order to obey the Law of Conservation of Mass.

(HS-PS1-3) 21st century themes: The use of technology through Pasco probes allows students to examine real time data and manipulate these data to derive relationships. Unit Rationale: The end of course exam for Biology covers topics that are not traditionally taught until after the test is administered. This unit is designed to allow the learner to experience some of the ecology and environmental science needed for the EOC prior to enrollment in the next year’s Biology course. Learning Targets Disciplinary Core Ideas: LS2.A: Interdependent Relationships in Ecosystems Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. Organisms would have the capacity to produce populations of great size were it not for the fact that environments and resources are finite. This fundamental tension affects the abundance (number of individuals) of species in any given ecosystem. (HS-LS2LS2.C: Ecosystem Dynamics, Functioning, and Resilience A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability. (HS-LS2-2), (HS-LS2-6) Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species. (HS-LS2-7) LS2.D: Social Interactions and Group Behavior Group behavior has evolved because membership can increase the chances of survival for individuals and their genetic relatives. (HS-LS2-8) LS4.C: Adaptation Changes in the physical environment, whether naturally occurring or human induced, have thus contributed to the expansion of some species, the emergence of new distinct species as populations diverge under different conditions, and the decline–and sometimes the extinction of some species. (HS-LS4-6) LS4.D: Biodiversity and Humans Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction). (secondary to HS-LS2-7) Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value. (secondary to HS-LS2-7), (HS-LS4-6) Science and Engineering Practices: Using Mathematics and Computational Thinking Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data.

Apply scientific ideas to solve a design problem, taking into account possible unanticipated effects. (HS-PS2-3) NGSS#: Next Generation Science Standard: HS-LS1-6 Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy. Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions. Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem. Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere. Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem. Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity. Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce. HS-LS1-7 HS-LS2-3 HS-LS2-4 HS-LS2-5 HS-LS2-6 HS-LS2-7 HS-LS2-8 Unit Essential Questions What is the importance of studying the interactions of living things and the environments in which they live? How does energy flow through the biosphere? How are nutrients recycled within a biosphere? Why are nutrient cycles essential to understanding the productivity of an ecosystem? Unit Enduring Understandings Ecological research provides information necessary to understand and resolve environmental and ecological issues. Energy in the form of sunlight flows through the tissues of primary producers to the tissues of consumers and finally to the tissues of decomposers. How does a food web explain the interdependence of living things on one another? What are the consequences of changes in the carbon cycle to plant and animal life on the planet? What factors affect the carrying capacity of a particular environment? Why does the rate of human population growth have a direct impact on the health of the Earth? A single nutrient such as phosphorus can have widespread damaging effects on plant and animal life. Industrial changes in human society which have affected the global carbon cycle are responsible for changes in Earth’s temperature. Density-dependent limiting factors include competition, predation, parasitism, and crowding and stress. Science, technology, and changes in society will help maintain Earth’s limited carrying capacity. Unit Learning Targets Students will ... Identify causes of ecological issues affecting the planet and design strategies aimed at solving these problems. Describe the need for sunlight (energy) in autotrophs and explain why plants are primary producers. Organize various trophic levels to show the dependence of consumers on producers.

Visually represent nutrient cycles (water, carbon, nitrogen) and explain the flow of each nutrient as it moves through the cycle. Study various natural and human-initiated carbon pathways and predict their impact on the planet. Formulate a course of action to minimize pollution and reduce atmospheric levels of carbon dioxide. Compare the effects of density-dependent versus density-independent limiting factors on population growth. Interpret predator/ prey relationship curves. Explain how both predator and prey have adapted to each other’s strengths and weaknesses. Predict changes in Earth’s natural resources and potential challenges humans will face if population growth continues at its current rate.
